LOCK-HANDLE MOUNTING.

Application led 'March 18, 1921. Sera1,No.453,415.

a washer or disk fastened to the face ofthe door, and heretofore this washer or disk has usually been fastened in place by several orf dinary wood screws, ordinarily from two to four in number. This has frequently served as an invitation to remove-the screws and the washer, thus making an unsightly place on the door; this invitation has -been especially strong incase ofthe inside knob of coin-controlled locks, because of the expected possibility of abstracting money from the lock through the hole thus opened.

It is the object of my invention to make it impossible to remove this disk or washer by fastening the washer in place by nonaccessible means, and at the same time to improve the appearance by eliminating the exposed fastening screws s0 that the washer or disk will be entirely smooth on its exposed surface. At the same time, it is my objectl by this same fastening means to lo,- cate the washer in a special position with respect to the lock proper so that the stem for the knob will necessarily be in proper alinement with the part which receives lit and binding 0f the lock by having these parts out of alinement will be avoided.

The accompanying drawing illustratesmy invention: Fig, 1 is an edge elevation of a part of a door provided with a coin-controlled lock in which the washer through which the stem of the inside knob projects is mounted in accordance with my invention, part of the door being in section and part of the lock casing being broken away; and Fig. 2 .is a section on a smaller scale on the line 2 2 of Fig. 1.

The door 10 has a lock plate 11 fastened to its outer face by screws 12, and on this lock plate is suitably mounted a lock casing 13, as shown by an interlocking tongue and groove 14 at the top and a'screw 15 at the bottom passing through a lugl projee-ting inward from the bottom of the casing and overlapping the lock plate 11. The casing 13 ts over and entirely conceals the locking plate 11. ltithin the casing` 13 is a* suitable locking mechanism, not shown, which locking mechanism may be operated either by an outside knob 17 or an inside knob or handle 18, the operation of the lock by theL knob 17 depending on some coin-control in thecase of*v many coiloperated locks.` The casing 13 is provi-ded at the bottom with a removable locked door 19, which is open to remove the accumulated coins, and through the opening of which access to the screw 15 is obtained.

The stem 20 for the inside knob 18 projects through the door into cooperation with a stem-receiving part 21 of the locking mechanism. `This stem passes through a disk or washer 22 which liesagainst the inner face of the door 10. This is the washer which has ordinarily heretofore been held in place by a. plurality of wood screws. I provide no wood screws for holding this washer in place, but make its outer surface entirely smooth. This washer has a central threaded hole 23, lwith the threads of which an externally threaded sleeve 241 passing through the door cooperates. The sleeve 24 loosely surrounds the stem 2,0, and is provided at its inner end with a polygonal head 25 which bears against the exposed face of the locking plate 12. By turning rthe sleeve 24C by its head 25, the washer 22 vis drawn tightly against the inner face of the door 10, and thehead 25 thus draw tightly .against the lockingplate 11. This is done from the outside, and can only be done when the lock casing 13 is removed. To prelvent possibility of turning the washer 24 while it is against the door 10, it is provided lwith an eccentrically located pin 26 which extends into a correspondingly vlocated hole 27 in the inner face of the door 10, asis clear from Fig. 1. The sleeve 24 is defi-` nitely located with respect to the lock plate 11,- and .so definitely locates the disk or washerv 22 with respect to such lock plate, to hold the stem 20 in proper alinement with the stem-receiving part 21' of the lock, without possibilityof these parts getting out ofalinenient and producing bindiluig of the lock'because of anyinaccuracy in putting inthe wood screws which are ordinarily used"for fastening the disk or ,washer in placev'lf-lie outer end of the stem 20 is carried in a sleeve'28 which is screw-mounted in the ilo- 2l; j )riiijecting'but part way through such hole to leave room for such other sleeve 2S. T he stein if() is freeljIv tui'nable Within the sleeve 2H, but is held against axial niovement relative thereto by `abutting` shoulders 2S) and by a. cross pin 30. After the Washer 22 has been put in place, and the casing; 18 with its locking parts have been inounted in place on the lock plate ll, the stein 20 is inserted through the Washer 22 and sleeve Q4 into the stem-receiving part 21, and the sleeve 28 is screwed into the outer end ot the hole 23. and preferably tightened by a suitable spanner wrench 'for which a hole 3l is provided. This makes a sight/ly construction. because oi the smoothness of the exposed face of the disk orfivasher 22, and makes it impossible to remove suohdisk or Washer from the inside ol? they door. v
